Closely derived from the two words smegma and osmosis, smegmosis is the process by which bits of annoying crapola, not necessarily smegma in the classical dictionary sense, move mysteriously from one location to another.
Tom: How did this load of smegmatic smegmoids get on my desk? They used to be on Julie's desk.
Ed: Ahh, the mysterious process of smegmosis has occured.
The uncanny ability of shit smell to transfer through 8-10 layers of quality toilet tissue to the wiper's hand,as if by osmosis. One tell-tale clue that you have acquired skinkmosis if if the wiping hand feels damp.
After pooping and wiping,I always do a stinkmosis sniff test to see if I need regular soap or germicidal gel or both.
